652 PARASITIC HYMENOPTERA, ii., 



the green merges into violaceous ; the antennal scape and four 

 front legs are yellow tinged with fulvous, especially on the 

 femora ; the hind legs are coloured as in the female, except 

 that the femora are green for the greater part ; and the tibia? 

 are not so deeply black, while their base may be testaceous. 

 The colour of the wings varies, some having the fuscous tint 

 on the apical two-thirds much lighter than others ; in the 

 males they may be almost hyaline. 



Tridyminse. 



Tepperella, gen.nov. 



Antennae short, stout, thickened towards the apex, appar- 

 ently 12-jointed, the basal joint of the flagellum longer than 

 broad, the apical shorter ; head wider than the thorax ; the 

 temples little developed, occiput broadly incised. Ocelli in a 

 curve, the hinder separated from each other by two-thirds 

 the distance they are from the eyes. Clypeus triangular, 

 longer than it is wide at the apex, which is transverse. Pro- 

 notum distinctly, but not largely developed, gradually 

 widened towards the apex. Mesonotum with the furrows 

 distinct, roundly curved ; its middle lobe larger than the 

 lateral, wide at the apex, which is bounded by a transverse 

 furrow. Scutellum large, nearly as long as the mesonotum, 

 gradually narrowed from the apex to the base, the apex 

 bluntly transverse. Metanotum short, obliquely sloped. 

 Abdomen broadly ovate, bkmtly rounded at the apex, shorter 

 than the thorax. Marginal nervure short, thick, about one- 

 quarter longer than the stigmal branch; postmarginal thinner, 

 and twice longer. Spurs short. Legs normal. There is a 

 distinct longitudinal furrow near the top of the mesopleurae, 

 extending from base to apex. 



Wings large, shortly ciliated round the apex. Malar space 

 as long as the eyes. Apex of clypeus transverse. The front 

 is little depressed. Top of antennal scape reaching close to 

 the ocelli. Body smoother than usual, being almost without
